Description

Part #: 23679B

Exact fit A, B or C pistons match your cylinder bore perfectly to maximize power and performance, while reducing blow-by and oil consumption. All piston kits include piston, rings, wrist pin and circlips required.

MIA's Description

A piston kit is only as reliable as its material composition and heat treatment—factors that directly impact engine longevity under sustained high RPM and boost conditions. The VERTEX Piston Kit 23679B delivers precision-engineered pistons with T-5 heat treatment and molybdenum disulfide skirt coating, giving you the durability and reduced friction needed for consistent performance and faster break-in cycles. Whether you're building a forced-induction engine or optimizing a naturally aspirated platform, these pistons provide the thermal stability and wear resistance that serious racers and high-output builds demand.
